Why San Diego for e-commerce & dtc: San Diego's biotech, defense tech, and tourism industries split into completely separate marketing playbooks. Persona-driven segmentation and channel selection (LinkedIn for biotech, Meta for tourism) are essential, not optional.

What e-commerce marketing agency actually means in San Diego

E-commerce marketing in 2026 is shaped by post-iOS 14.5 attribution challenges, rising acquisition costs, and the increasing importance of retention economics. Brands competing only on paid acquisition without retention infrastructure don't survive.

Empire325 e-commerce engagements combine paid acquisition, retention email (Klaviyo/Customer.io), CRO, and full-warehouse marketing attribution — driving 20-40% blended CAC reduction through reallocation away from over-credited channels.
